ObjectiveTo discuss a case series of Actinomyces infection post‐rhinoplasty and review the literature for correct diagnosis and management.Study DesignCase series with chart review.MethodsThree cases are presented of patients with a history of recurrent infectious symptoms post revision rhinoplasty later being diagnosed as Actinomyces.ResultsThree patients were identified having undergone revision rhinoplasty and later being diagnosed with Actinomyces infection. They initially presented with underwhelming physical exams, mild erythema, slight swelling, yet extreme pain. They also had periods of recurrent infection once antibiotics were stopped. Aerobic, anaerobic, fungal, and Actinomyces cultures were sent to pathology and returned positive for Actinomyces. Treatment typically involved a combination of prolonged antibiotics, incision and drainage, and/or surgical debridement.ConclusionsAwareness of Actinomyces as a possible cause of infection post‐rhinoplasty is significant as this pathogen can lead to extensive tissue destruction and fistula formation which could be detrimental for a rhinoplasty. Duration of treatment is beyond typical lengths for other infections and a specific culture for Actinomyces is required to be sent as it isn't captured in standard aerobic/anaerobic cultures. Therefore, a high index of suspicion is required by physicians to ensure that patients are evaluated thoroughly. Laryngoscope, 133:2948–2950, 2023

Abstract Background With data demonstrating benefit, the prevalence of home enteral nutrition (HEN) has increased significantly over the last few decades. Despite this increase, there remains a paucity of data regarding real‐world use of HEN including clinical outcomes and complications. Methods Descriptive analysis of prospectively maintained database of our specialized HEN program was undertaken. Patients who received care in our program with HEN initiation date between January 1, 2018, and December 31, 2020, were included in the analysis. Data regarding demographic information, anthropometrics, enteral nutrition (EN) regimen, electrolytes, and nutrition therapy history were included and tracked until July 31, 2021. Results During the study period, 1600 patients initiated HEN treatment under our care. Majority of the study population needed EN therapy due to malignancy and its complications, including malignant dysphagia or mechanical obstruction (60.6%) followed by neurodegenerative diseases (7.5%). By the end of the study period, a majority of the patients (82%) stopped HEN treatment. Of these, 44.2% achieved EN goals and/or oral autonomy. Patients continued HEN treatment for a median of 100 (interquartile range, 32–301) days. Overall, 53.2% of patients experienced/reported at least one HEN‐related complication that was clinically managed by the HEN team. Complications included tube‐related, enteral feeding intolerance (EFI), and electrolyte shifts. Conclusion In our study population, HEN was most utilized to manage malignancy‐related complications, including dysphagia. Unfortunately, complications, including EFI and tube‐related complications, remained quite prevalent. Further evaluation regarding risk factors for complications and preventive mechanisms, such as increased education, is indicated.

Context.— Antibodies to U1 ribonucleoprotein (U1RNP) were first described more than 50 years ago, and although clinically relevant for antinuclear antibody–associated connective tissue disease (ANA-CTD), test results are challenging to interpret. Objective.— To evaluate the impact of anti-U1RNP analyte diversity in the assessment of patients at risk for ANA-CTD. Design.— Two multiplex assays for U1RNP (Smith [Sm]/RNP and RNP68/A) were used to test serum specimens from consecutive patients (n = 498) under evaluation for CTD in a single academic center. Discrepant specimens were further tested for Sm/RNP antibody by enzyme-linked immunosorbent assay and the BioPlex multiplex assay. Data were evaluated for antibody positivity per analyte and their method of detection, correlations between analytes, and impact on clinical diagnoses through retrospective chart review. Results.— Of the 498 patients tested, 47 (9.4%) were positive in the RNP68/A (BioPlex) and 15 (3.0%) were positive in the Sm/RNP (Theradiag) immunoassays. U1RNP-CTD, other ANA-CTD, and no ANA-CTD were diagnosed in 34% (16 of 47), 12.8% (6 of 47), and 53.2% (25 of 47) of the cases, respectively. The prevalence of antibody by method in patients with U1RNP-CTD was 100.0% (16 of 16), 85.7% (12 of 14), 81.5% (13 of 16), and 87.5% (14 of 16) for RNP68/A, Sm/RNP BioPlex, Sm/RNP Theradiag, and Sm/RNP Inova, respectively. For other ANA-CTD and no ANA-CTD, the highest prevalence was observed with RNP68/A; all others had comparable performance. Conclusions.— In this study, the overall performance characteristics of Sm/RNP antibody assays were comparable; however, the RNP68/A immunoassay was very sensitive but less specific. In the absence of harmonization, reporting the type of U1RNP analyte in clinical testing may be useful in guiding interpretation and interassay correlations.

Abstract Purpose: To assess whether MUC1 peptide vaccine produces an immune response and prevents subsequent colon adenoma formation. Patients and Methods: Multicenter, double-blind, placebo-controlled randomized trial in individuals age 40 to 70 with diagnosis of an advanced adenoma ≤1 year from randomization. Vaccine was administered at 0, 2, and 10 weeks with a booster injection at week 53. Adenoma recurrence was assessed ≥1 year from randomization. The primary endpoint was vaccine immunogenicity at 12 weeks defined by anti-MUC1 ratio ≥2.0. Results: Fifty-three participants received the MUC1 vaccine and 50 placebo. Thirteen of 52 (25%) MUC1 vaccine recipients had a ≥2-fold increase in MUC1 IgG (range, 2.9–17.3) at week 12 versus 0/50 placebo recipients (one-sided Fisher exact P < 0.0001). Of 13 responders at week 12, 11 (84.6%) responded to a booster injection at week 52 with a ≥2-fold increase in MUC1 IgG measured at week 55. Recurrent adenoma was observed in 31 of 47 (66.0%) in the placebo group versus 27 of 48 (56.3%) in the MUC1 group [adjusted relative risk (aRR), 0.83; 95% confidence interval (CI), 0.60–1.14; P = 0.25]. Adenoma recurrence occurred in 3/11 (27.3%) immune responders at week 12 and week 55 (aRR, 0.41; 95% CI, 0.15–1.11; P = 0.08 compared with placebo). There was no difference in serious adverse events. Conclusions: An immune response was observed only in vaccine recipients. Adenoma recurrence was not different than placebo, but a 38% absolute reduction in adenoma recurrence compared with placebo was observed in participants who had an immune response at week 12 and with the booster injection.

Abstract Background In the United States, rare disease (RD) is defined as a condition that affects fewer than 200,000 individuals. Collectively, RD affects an estimated 30 million Americans. A significant portion of RD has an underlying genetic cause; however, this may go undiagnosed. To better serve these patients, the Mayo Clinic Program for Rare and Undiagnosed Diseases (PRaUD) was created under the auspices of the Center for Individualized Medicine (CIM) aiming to integrate genomics into subspecialty practice including targeted genetic testing, research, and education. Methods Patients were identified by subspecialty healthcare providers from 11 clinical divisions/departments. Targeted multi-gene panels or custom exome/genome-based panels were utilized. To support the goals of PRaUD, a new clinical service model, the Genetic Testing and Counseling (GTAC) unit, was established to improve access and increase efficiency for genetic test facilitation. The GTAC unit includes genetic counselors, genetic counseling assistants, genetic nurses, and a medical geneticist. Patients receive abbreviated point-of-care genetic counseling and testing through a partnership with subspecialty providers. Results Implementation of PRaUD began in 2018 and GTAC unit launched in 2020 to support program expansion. Currently, 29 RD clinical indications are included in 11 specialty divisions/departments with over 142 referring providers. To date, 1,152 patients have been evaluated with an overall solve rate of 14.1% and as high as 66.7% depending on the phenotype. Noteworthy, 42.7% of the solved or likely solved patients underwent changes in medical management and outcome based on genetic test results. Conclusion Implementation of PRaUD and GTAC have enabled subspecialty practices advance expertise in RD where genetic counselors have not historically been embedded in practice. Democratizing access to genetic testing and counseling can broaden the reach of patients with RD and increase the diagnostic yield of such indications leading to better medical management as well as expanding research opportunities.

Abstract Background. Patient-reported outcomes (PROs) are increasingly recognized as a valuable component to understand treatment tolerability and toxicity among patients on clinical trials. We have implemented a system for monitoring patient reported outcomes (PROs), symptoms, and quality of life (QOL) using electronic PRO (ePRO) instruments for patients enrolled in the I-SPY2 trial. I-SPY2 is a phase II multi-site clinical trial evaluating the effect of novel neoadjuvant therapies for locally advanced breast cancer. We correlated patient demographic factors with symptoms, investigated the trajectory of symptoms throughout treatment, and sought to characterize symptoms associated with decline in physical function (PF). Methods. Our study population included 259 I-SPY2 patients that completed surveys on one of 9 study arms (including novel oral taxane/immunotherapy combinations, IV paclitaxel, checkpoint inhibitor+/- LAG3 inhibitor, and control IV paclitaxel +/- trastuzumab/pertuzumab). After the 12 week period of investigational agents, most patients received standard adriamycin and cyclophosphamide (AC). Symptom severity, frequency, and interference was assessed weekly using 33 items from the PRO-CTCAE item bank. PF was assessed using the NIH PROMIS instrument and was evaluated at baseline, inter-regimen (after 12 weeks of treatment), pre-surgery, and 1 and 6 months at follow-up. An odds ratio was used to assess univariate associations between age and race, and symptoms. Regularized multi-variate regression was used to evaluate early symptoms (prior to week 6) predictive of a clinically significant (>5 point T-score) decline in PF from baseline to post-treatment follow-up among all races and age groups. Results. Of 259 patients (mean age (SD) = 46.8 (13.6)), 160 (58%) were White, 13 (5%) were Asian, 26 (10%) were African American (AA), 25 (9.3%) were Hispanic, and 35 (13.5%) self-reported “Other”. At baseline, AA patients had a higher severity of joint pain than White patients (OR = 14.9, P < 0.05). During study treatment with paclitaxel and/or novel agent within the first 12 weeks of treatment, AA patients and non-white (NW) patients were more likely to report severe vomiting than White patients (OR =13.22 and 12.72, P< 0.05 and P< 0.03 respectively). During treatment with AC, NW patients were more likely to report higher severity of neuropathy than White patients (OR = 5.43, P< 0.03). Among all patients, in analysis of early symptoms predictive of a clinically significant decline in PF between baseline and 1 month post treatment, predictors included high frequency of diarrhea, severity of itching, and severity of joint pain. Further analysis of symptom trajectories revealed that frequency of diarrhea reported rose sharply between baseline and Cycle 2 with 9 patients (7%) reporting occasional or frequent diarrhea to 39 patients (28%) reporting occasional to almost constant diarrhea and remained stable at that proportion for the remainder of treatment. Frequency of diarrhea declined slightly during AC (17%) and dropped to baseline levels by follow-up. In contrast, severity of joint pain persisted post-treatment, rising consistently from baseline through follow- up with 3 patients (2%) reporting moderate to severe joint pain at baseline to 18 patients (35%) reporting moderate to severe joint pain at follow-up. Conclusion. Among I-SPY2 participants, when higher grade of diarrhea is persistent (or uncontrolled), it impacts physical function even after end of therapy. In some cases, race was also a determinant in symptom trajectory, although a higher enrollment of AA and NW patients will enable more robust estimates to be computed. While some of these early symptom predictors are transient and resolve by the time of follow-up, others persist long-term and contribute more directly towards impaired physical function at follow-up.

Abstract Purpose: We previously demonstrated that high levels of circulating methylated DNA are associated with subsequent disease progression in women with metastatic breast cancer (MBC). In this study, we validated the clinical utility of a Liquid Biopsy-Breast Cancer Methylation (LBx-BCM) prototype assay using the GeneXpert® cartridge system for early assessment of disease progression in MBC. Study Design: The 9-marker, LBx-BCM prototype assay was evaluated in TBCRC-005, a prospective biomarker study, using plasma collected at baseline, week 4 and week 8 from 144 MBC patients. Results: At week 4 MBC patients with high cumulative methylation (CM) had a significantly shorter median PFS (2.88 months v 6.60 months, p = 0.001) and OS (14.52 months v 22.44 months, p=0.005) compared to those with low CM. In a multivariable model, high versus low CM was also associated with shorter PFS (HR = 1.90, 95%CI 1.20-3.01; p =0.006). Change in CM from baseline to week 4 (OR = 4.60, 95%CI 1.77, 11.93; p = 0.002) and high levels of CM at week 4 (OR = 2.78, 95%CI 1.29, 5.99; p = 0.009) were associated with progressive disease at the time of first restaging. A robust risk model (AUC = 0.733) based on week 4 circulating CM levels was developed to predict disease progression as early as 3 months after initiating a new treatment. Conclusion: The easy to perform and automated LBx-BCM prototype assay is a promising clinical tool for detecting disease progression early after initiating treatment in women with MBC. Further validation in larger clinical datasets is needed. Citation Format: Kala Visvanathan, Leslie Cope, Mary Jo Fackler, Michael Considine, Lisa Carey, Andres Forero-Torres, James N.

Abstract Background: Despite evidence of substantial breast cancer risk reduction, few high-risk women adopt chemopreventive medications such as selective estrogen receptor modulators (SERMs) or aromatase inhibitors (AIs). Women with benign breast disease, such as atypical hyperplasia (AH) or lobular carcinoma in situ (LCIS), have an increased risk of developing breast cancer and derive a greater benefit from antiestrogens compared to other high-risk women. Reasons for low uptake of chemoprevention include insufficient patient and clinician knowledge about antiestrogens, time constraints during the clinical encounter, and concerns about side effects. To address these barriers, we have developed patient and provider web-based decision support tools to improve informed choice about breast cancer chemoprevention among women with AH or LCIS. Study design: We are conducting a cluster-randomized controlled trial of clinical decision support to improve chemoprevention informed choice among women with AH or LCIS and their treating providers. Twenty-six U.S. sites through the SWOG Cancer Research Network were randomly assigned 1:1 to standard educational materials alone or in combination with the patient-centered decision aid (RealRisks) and provider decision support tool (BNAV). A total of 415 patients and 200 healthcare providers will be recruited from these sites. RealRisks consists of interactive modules to calculate personalized breast cancer risk and elicit preferences on chemoprevention. The modules are available in English and Spanish. BNAV is comprised of self-directed case-based learning modules on breast cancer risk assessment and chemoprevention. Patients complete questionnaires at baseline, 6 and 12 months. Providers complete surveys at baseline and after their enrolled patient’s 6-month clinical encounter. The primary endpoint is chemoprevention informed choice at 6 months, using a measure combining knowledge, attitude, and intention scales. Secondary endpoints include perceived breast cancer risk/worry, chemoprevention knowledge/intention, decision conflict/regret, shared decision-making, and chemoprevention uptake. For patients who begin chemoprevention, adherence and reasons for discontinuation are assessed annually for up to 5 years. Barriers and facilitators to implementing RealRisks and BNAV into clinic workflow will be assessed by conducting patient and provider interviews at baseline and mid-implementation. Eligibility criteria: Eligible patients include women, age 35-74 years, with AH or LCIS, no history of breast cancer, no prior use of SERMs or AIs, no bilateral mastectomies, English or Spanish-speaking, and access to the internet. Eligible providers include breast surgeons, medical oncologists, primary care providers, and physician extenders who see patients with AH or LCIS. Statistical methods: We have 90% power to detect a 15% increase in the frequency of chemoprevention informed choice with a 1-sided 0.025 level test, assuming an intraclass correlation (ICC) of 0.02 to account for clustering, roughly equal accrual at each site, 10% loss to follow-up, and ≤10% event rate in the control arm. Current/target accrual: The trial was activated on 9/1/2020. As of 7/7/2022, all 26 sites have been randomized, 157/200 providers and 184/415 patients have been enrolled. Discussion: Our hybrid effectiveness/implementation study seeks to evaluate the effectiveness of a multi-level intervention in promoting informed decision-making about breast cancer chemoprevention. Study results will provide valuable insights on how the decision support tools are integrated in diverse clinical settings. Citation Format: Katherine D.

Abstract Background Breast conserving therapy (BCT) is accepted as a preferred option for unifocal breast cancer. However, the oncologic safety of BCT for multiple ipsilateral breast cancer (MIBC), has not been demonstrated in a prospective study. The ACOSOG (Alliance) Z11102 phase II single arm prospective trial was designed to evaluate outcomes with BCT for MIBC. Methods Women age 40+ with 2 or 3 foci of biopsy proven breast cancer (BC) (each site < 5cm in size with at least 1 site invasive) separated by >2-3 cm of normal breast tissue and disease limited to two quadrants of the breast with cN0 or cN1 disease were eligible. All patients had pre-operative mammogram and breast MRI was initially required and subsequently made optional. Neoadjuvant therapy was not allowed. Patients were treated with lumpectomy resected to negative margins followed by whole breast radiation with boost to all lumpectomy beds. The primary endpoint of Z11102 is the cumulative incidence of local recurrence (LR, defined as histologic evidence of ductal carcinoma in situ or invasive BC in the ipsilateral breast or chest wall) at 5 years (treating death and distant and nodal/regional recurrence as competing risks) to assess whether the rate is greater than 8%. Data were frozen 5/25/2022. Results From 11/2012-8/2016, 270 women were enrolled. Of these, 33 were ineligible, 14 converted to mastectomy, 11 were unable to meet protocol-specific radiation endpoints, 1 had no definable tumor, 1 had 4 sites of cancer and 16 withdrew before completing surgery and radiation, leaving 194 patients [median age 61 (range 40-87)] eligible who completed breast conserving surgery and radiation therapy. With median follow-up of alive patients of 66.6 months (range: 4.1, 90.6), 6 patients have developed LR (5 ipsilateral breast and 1 chest wall), corresponding to an estimated cumulative incidence of local recurrence of 3.2% (95% CI: 1.3, 6.4) at 5 years. No patients have developed regional recurrence, 5 patients developed distant recurrence, 0 patients developed local and distant recurrence, 5 patients developed contralateral BC, 3 new non-BC primaries and 8 patients have died (1 related to BC). The rate of local recurrence in patients without a breast pre-op MRI (n=14) was 22.6% at 5 years compared to 1.7% among the 180 patients with a preop MRI (p=0.002). Patient age, number of sites of preoperative biopsy proven BC, HER2 status, pathologic T and N category were not statistically significantly associated with risk of LR. Conclusion The Z11102 clinical trial demonstrates that for women with MIBC breast conserving surgery with adjuvant radiation with lumpectomy site boosts has an acceptably low LR rate (3.2% at 5 years), making this a reasonable consideration for women with 2-3 ipsilateral foci. The LR rate was significantly higher in the small cohort of patients without preoperative breast MRI. Support: U10CA180821, U10CA180882; https://acknowledgments.alliancefound.org.
